Title: Combustion apparatus for atmosphere of continuous nonoxidation heat treating furnace
Inventor: AMANO MASAZANE
IPC: F27B9/12
Filed: 1979-08-25
Abstract: PURPOSE:To utilize combustion heat of atmosphere gas effectively without disturbing the atmosphere in a heating furnace, by providing a continuous nonoxidation heat treating furnace with  seasoning chamber and a preheating chamber, by burning the atmosphere gas, which has been  used, in a combustion chamber arranged above the preheating chamber, and by discharging the  combustion gas to outside of the furnace. CONSTITUTION:A seasoning chamber 10 and a preheating chamber 4 are installed in series to a  continuous nonoxidation heat treating furnace 12, and a work to be treated is charged through  the inlet 14 of the preheating chamber 4 by a belt conveyor 5. Above the preheating chamber 4, a  combustion chamber 6 is partitioned by a heatresistant steel plate 15, and the combustion chamber 6 is equipped with plural air intake pipes 8 and an exhaust duct 9. The atmosphere gas discharged from the heating chamber 12 enters through the seasoning chamber 10 and the preheating chamber 4 into the combustion chamber 6, where it is burned with air introduced through the air  intake pipes 8, and the waste gas is discharged through the exhaust duct 9. The steel plate 15  heated by the combustion radiates heat thereby preheating the work and improving the heat efficiency. Because the exhaust gas scarcely flows inversely into the heating chamber, degradation  in hardening quality of the work dut to the disturbance of the atmosphere is prevented.

Abstract: PURPOSE: To improve separation efficiency of a centrifuge, which collects dust by inducing a gas contg. dust to flow into a cylinder, and by rotating the cylinder at a speed equal to the circumferential speed of the gyratory flow in the cylinder.  
     CONSTITUTION: A gas contg. dust flows into a cylinder 2 through an inlet opening 3 installed tangentially at the inlet of the cylinder 2, then flows while revolving through inside of a separating cylinder section 8 to the other end. The dust is collected in a collecting chamber 4 through the slit 6 formed between a base disc 5 and the internal wall of the collecting chamber 4, while the gas turns round and flows near the center axis then it is discharged through an outlet 15 installed at the inside of the inflow section 1. The cylinder section 2 is rotated in the gyrating direction of the fluid and at a circumferential speed nearly equal to the speed of gyratory flow. Hereby the friction loss between the gas and the cylinder wall is reduced remarkably, so that the gyratory flow is stabilized, and the separation efficiency is increased.
